Next, the operation of the construction support system 90 according to the present embodiment will be described with reference to FIGS. 11 to 27. First, with reference to FIGS. 11 to 13, the operation of the construction support device 10 when executing the construction plan creation process, which is the process of creating the construction plan, will be described. When the CPU 11 of the construction support device 10 executes the construction plan creation program 13A in response to the execution instruction of the construction plan creation process being input to the construction support device 10, the construction plan creation process shown in FIG. 11 is performed. Will be executed. In order to avoid complications, a case where the construction site for which the construction plan is created (hereinafter referred to as “planning target site”) is specified in advance will be described here.

In step 200 of FIG. 11, the acquisition unit 11A reads all the information (hereinafter referred to as “required skill information”) from the required skill information database 33A, and reads all the information (hereinafter referred to as “required skill information”) from the builder-specific skill information database 33B. "Skill information for each builder") is read. Further, in step 200, the acquisition unit 11A reads out all the information (hereinafter, referred to as “standard working time information for each builder”) from the standard working time database 33C for each builder.

In the next step 202, the acquisition unit 11A reads out information about the construction process (hereinafter, referred to as “construction process information”) from the navigation information database 33F. In the next step 204, the acquisition unit 11A reads all the information (hereinafter referred to as “construction schedule information”) from the construction schedule information database 33D and all the information (hereinafter referred to as “construction plan information”) from the construction plan information database 33E. ".) Is read.

In the following, the planned construction schedule corresponding to the planned site in the construction schedule information is referred to as "planned schedule", and the housing type corresponding to the planned site in the construction schedule information is referred to as "planned housing type". In the following, the number of units corresponding to the planned site in the construction schedule information is referred to as "planned number of units", and the construction process indicated by the construction process information is referred to as "planned construction process".

In the next step 206, the creation unit 11B determines whether or not the construction schedule included in the read construction plan information has a schedule that matches the plan target schedule, so that the planned construction is performed on the plan target schedule. It is determined whether or not there is, and if a negative determination is made, the process proceeds to step 210, while if an affirmative determination is made, the process proceeds to step 208.

In step 208, the creation unit 11B identifies the builder who performs the construction on the construction schedule determined to match the plan target schedule in step 206 from the construction plan information, and refers to the builder (hereinafter referred to as “set builder”). ) Is excluded from this construction plan. In the present embodiment, as the builder exclusion process, a process of temporarily storing the builder ID corresponding to the set builder in a predetermined area of the storage unit 13 is applied, but the process is not limited to this. Needless to say. In the following, the builder excluding the set builder is referred to as the "settable builder".

In step 210, the creation unit 11B identifies the construction process to be planned from the read construction process information, and in the next step 212, the creation unit 11B is the construction object (unit bath in this embodiment) at the site to be planned. Create a construction plan as shown below. Here, in order to avoid complications, regarding the process of "fitting confirmation" in the planned construction process, "fitting" is not considered in the subdivided processes such as "height measurement" and "window measurement". It will be described as a process summarized as "confirmation".

First, the creation unit 11B specifies the most important required skill corresponding to the planned target housing type in the required skill information for each process of the planned target construction process specified by the process of step 210. For example, when the type of residence to be planned is an apartment house, "cautiousness" is specified for "confirmation of fit" and "construction speed" is specified for "floor" as the most important required skill.

Next, the creation unit 11B applies a settable builder having a high skill value corresponding to the corresponding most important required skill as a construction candidate for each process of the specified planned construction process. At this time, it is permissible to apply different settable installers to the same construction process, and to apply the same configurable installer to different construction processes. In the present embodiment, as a configurable builder with a high skill value, a builder whose skill value indicated by the skill information for each builder is a predetermined value (70 as an example) or more is applied. Not limited. For example, among the configurable installers, the installers having the highest corresponding skill value to the predetermined number of installers may be applied as the configurable installers having the highest skill values.

In addition, the creation unit 11B specifies the standard work time corresponding to the applied construction candidate for each process of the construction target process from the standard work time information for each contractor, and sets the number of units to be planned in the specified standard work time. Is multiplied by the value obtained by dividing by the number of construction candidates applied to the corresponding process, and the work time required for each construction candidate to carry out the process is calculated. Then, by adding up the work time of each construction candidate for each process of the planned construction process, the estimated work time for each process expected to be spent in each process is calculated. Information indicating the construction candidates for each process and the estimated work time for each process with respect to the construction process to be planned obtained by the above processing is referred to as "provisional plan information".

In the next step 214, the creation unit 11B determines whether or not the total work time of the planned target construction process indicated by the provisional plan information obtained by the process of step 212 is within the range of the planned target schedule. If the result is affirmative, the process proceeds to step 216.

In step 216, the creation unit 11B stores (registers) the provisional plan information obtained by the above processing in the construction plan information database 33E as information indicating the final construction plan corresponding to the planned site. In the next step 218, the creation unit 11B transmits information indicating the created construction plan to the terminal 20 owned by each builder via the communication I / F unit 18. In the next step 220, the creation unit 11B uses the created construction plan to control the display unit 15 so as to display the construction plan display screen in a predetermined format, and then the main construction plan creation process. To finish.

As shown in FIG. 12, in the present embodiment, as the construction plan display screen, the construction candidates and the names of the processes corresponding to each process are in chronological order from the left side to the right side of the paper, and the construction time zone ( Estimated work time for each process) is displayed so that it can be understood. Therefore, the user of the construction support device 10 who has referred to the construction plan display screen can easily grasp the process to be carried out by each builder and the time zone to be carried out.

Further, also on the terminal 20 that has received the information indicating the construction plan, the same construction plan display screen as that shown in FIG. 12 is displayed on the display unit 25 as an example. Therefore, the builder who has referred to the construction plan display screen can easily grasp the process to be carried out by himself / herself and the time zone to be carried out.

On the other hand, if a negative determination is made in step 214, the process proceeds to step 222, and the creation unit 11B determines whether or not there are any configurable installers that have not been applied in the immediately preceding fit, thereby determining the provisional plan information. It is determined whether or not there is room for the contractor to rearrange the item, and if the determination is positive, the process returns to step 212. In step 212, which is executed subsequently from this process, the settable builder is applied to each step of the planned construction process including the remaining settable builder.

On the other hand, if a negative judgment is made in step 222, it is assumed that the required construction plan cannot be created by the current personnel, and the process proceeds to step 224, and the creation unit 11B displays a predetermined personnel shortage. After controlling the display unit 15 so as to display the screen, the present construction plan creation process is terminated.

As shown in FIG. 13, in the present embodiment, the construction site, the type of residence, the scheduled construction schedule, the skills and the number of people required for the contractor who will be short of staff, and the shortage time are displayed as the staff shortage display screen. .. Therefore, the user of the construction support device 10 who has referred to the personnel shortage display screen can efficiently add personnel, review the overall plan, and the like based on this information.

Next, with reference to FIGS. 14 to 23, the construction support device 10 and the terminal when executing the process of supporting the work when each builder performs the construction according to the construction plan created by the construction plan creation process. The action of 20 will be described. In this case, the construction support process shown in FIG. 14 is performed by the CPU 11 of the construction support device 10 executing the construction support program 13B in response to the input of the construction support process execution instruction to the construction support device 10. Will be executed. Further, in this case, the navigation process shown in FIG. 15 is executed by the CPU 21 of the terminal 20 executing the navigation program 23A in response to the builder inputting the execution instruction of the navigation process to the terminal 20. To. First, with reference to FIG. 14, the operation of the construction support device 10 when executing the construction support process will be described.

Each builder who performs construction according to the construction plan created by the construction plan creation process goes to the construction site where he / she performs the construction, and causes his / her terminal 20 to execute the navigation process as described later. Then, in this navigation process, the builder transmits the navigation request information for requesting the navigation service to the construction support device 10 together with the site information indicating the construction site, his / her own builder ID, and the language information indicating the language to be used. Perform the operation to do.

Therefore, in step 300 of FIG. 14, the presentation unit 11G waits until the navigation request information is received from any terminal 20, and then waits until the navigation service is requested from any terminal 20. In the following, the terminal 20 from which the navigation request information received here is transmitted is referred to as a "corresponding target terminal", and the builder who owns the corresponding target terminal is referred to as a "corresponding target builder".

In the next step 302, the presentation unit 11G reads all the information (hereinafter referred to as "navigation information") from the navigation information database 33F. In the next step 304, the presentation unit 11G uses the read navigation information to create information indicating a navigation screen in a predetermined format (hereinafter, referred to as “navigation screen information”). In the next step 306, the presentation unit 11G transmits the created navigation screen information to the corresponding target terminal via the communication I / F unit 18. At this time, the presentation unit 11G creates navigation screen information indicating a navigation screen corresponding to the language indicated by the language information received together with the navigation request information. Further, at this time, the presentation unit 11G creates navigation screen information as information indicating a plurality of screens, which are different pages for each process indicated by the read navigation information.

Upon receiving the navigation screen information, the corresponding target terminal controls the display unit 25 of itself to display the navigation screens shown in FIGS. 17 to 20 as different pages for each process by using the received navigation screen information. To do. When the navigation screen is displayed on the corresponding target terminal, the corresponding target terminal shows the measurement result of the position of each part in the process of "fitting confirmation" according to the operation by the corresponding target builder, as described later. , The inspection result information indicating the inspection result for the construction carried out in the process related to the installation of the construction object (in this embodiment) and the individual process completion information indicating the completion of the individual process are transmitted to the construction support device 10. To do. In this embodiment, when the designated input for specifying the start of execution of the next process is accepted on the navigation screen, the individual process end information indicating that the immediately preceding process is completed is transmitted to the construction support device 10. However, it is not limited to this. For example, the navigation screen is set to accept a designated input for designating the end of the process when each process is completed, and when the designated input is accepted, individual process end information indicating that the process is completed is provided. It may be in the form of transmitting to the construction support device 10.

Therefore, in the next step 308, the reception unit 11H determines whether or not the measurement result information has been received from the corresponding target terminal, and if a positive determination is made, the process proceeds to step 310. In step 310, the reception unit 11H stores the received measurement result information in a predetermined area of the storage unit 13, and then proceeds to step 316.

On the other hand, if a negative determination is made in step 308, the process proceeds to step 312, the reception unit 11H determines whether or not the inspection result information has been received from the corresponding target terminal, and if a negative determination is made, the process proceeds to step 316. On the other hand, if a positive judgment is made, the process proceeds to step 314. In step 314, the reception unit 11H stores the received inspection result information in a predetermined area of the storage unit 13, and then proceeds to step 316.

In step 316, the delay estimation unit 11C determines whether or not the individual process end information has been received from the corresponding target terminal, and if a positive determination is made, the process proceeds to step 318. At this time, when a plurality of contractors are applied to the process corresponding to the individual process end information, the delay estimation unit 11C determines whether or not the last individual process end information for the process has been received. judge.

In step 318, the delay estimation unit 11C determines whether or not the process indicated by the received individual process end information (hereinafter, referred to as “end process”) is completed within a predetermined time (10 minutes in the present embodiment) from the schedule. To judge. Then, the delay estimation unit 11C shifts to step 336 when a positive judgment is made here, while when a negative judgment is made, the construction to be supported is delayed from the construction time planned in the construction plan. Then, it is estimated, and the process proceeds to step 320. In this embodiment, it is determined as follows whether or not the end process is completed within a predetermined time from the schedule.

That is, the delay estimation unit 11C refers to the end time in the construction schedule of the corresponding process in the construction plan information database 33E, and the time when the individual process end information is received is within the above-mentioned predetermined time with respect to the end time. By determining whether or not the process is completed, it is determined whether or not the end process is completed within a predetermined time from the schedule.

In step 320, the instruction unit 11D determines whether or not there is a suitable construction person who is not engaged in the remaining process for the process after the end process (hereinafter, referred to as “remaining process”), and determines affirmatively. If it becomes, the process proceeds to step 322. In this embodiment, it is determined as follows whether or not the above-mentioned suitable person for construction exists.

That is, the instruction unit 11D first refers to the construction plan information database 33E, and identifies the contractors (hereinafter, referred to as “suitable candidates for construction”) excluding the contractors engaged in the remaining processes. Next, the instruction unit 11D identifies the most important requirement skill of the remaining process by referring to the requirement skill information database 33A, and there is a construction suitable candidate having a high skill value corresponding to the identified most important requirement skill. By determining whether or not, it is determined whether or not the above-mentioned suitable person for construction exists. In this embodiment, as a construction suitable candidate with a high skill value, a construction suitable candidate whose corresponding skill value is specified by the skill information database 33B for each contractor is a predetermined value (70 as an example) or more. However, it goes without saying that it is not limited to this.

In step 322, the instruction unit 11D transmits the support instruction information instructing the construction support of the remaining process to the terminal 20 of the construction qualified person via the communication I / F unit 18 together with the information indicating the support content. Upon receiving the support instruction information, the terminal 20 executes the support process (see FIG. 22) described later, and displays the support request screen (details will be described later) shown in FIG. 23 on the display unit 25 as an example. Then, the contractor whose support request screen is displayed on the terminal 20 specifies whether or not to provide support on the support request screen, thereby providing construction support with support status information indicating whether or not to provide the support. It is transmitted to the device 10 to provide the support displayed on the support request screen. In addition, here, in order to avoid complications, a case where at least one of the qualified construction personnel provides support will be described.

Therefore, in the next step 324, the change unit 11E waits until the support status information is received from all the terminals 20 that have transmitted the support instruction information. Then, the change unit 11E changes the corresponding construction plan of the construction plan information database 33E so as to reflect that the construction qualified person who provides the support engages in the remaining process by using the received support status information. After that, the process proceeds to step 328.

On the other hand, if a negative determination is made in step 320, the process proceeds to step 326, and the changing unit 11E changes the end time of the end process to the actual end time, and the construction schedule of the remaining process is also the end time of the end process. The corresponding construction plan of the construction plan information database 33E is changed so as to be sequentially moved down according to the actual end time, and then the process proceeds to step 328.

In step 328, the change unit 11E transmits information indicating the changed construction plan to the terminal 20 of the builder engaged in the corresponding construction, and then proceeds to step 336. The terminal 20 that has received the information indicating the changed construction plan displays the information indicating the changed construction plan on the display unit 25. Therefore, by referring to this display, the builder who is performing the corresponding construction can grasp the change of the construction plan that he / she is making or plans to make.

On the other hand, if a negative determination is made in step 316, the process proceeds to step 330, and the detection unit 11F determines whether or not the work efficiency of the construction process being carried out is below a predetermined level. It is determined whether or not the process has passed in the process being carried out, and if a negative determination is made, the process returns to step 308, while if an affirmative determination is made, the process proceeds to step 332. In this embodiment, the reference time is determined as follows.

That is, the detection unit 11F first sets the standard working time of the corresponding construction process for all the contractors engaged in the construction process being carried out (hereinafter referred to as "engaged contractor") as the standard work for each contractor. Read from time database 33C. Next, the detection unit 11F multiplies the read standard working time by the number of times the corresponding construction process is performed by the corresponding worker for each worker. Then, the detection unit 11F sets the maximum time of the construction time for each engaged worker obtained by the above calculation as the reference time. However, the present invention is not limited to this form, and for example, a time obtained by multiplying the maximum time by a predetermined coefficient (for example, 1.2) may be applied as the reference time.

In step 332, the presentation unit 11G extracts the advice text and the advice voice corresponding to the corresponding construction process from the read navigation information, and uses the extracted advice text to display the advice screen in a predetermined format. Create advice screen information to show. Then, in the next step 334, the presentation unit 11G transmits the created advice screen information and the extracted advice voice to the terminal 20 of the engaged contractor via the communication I / F unit 18, and then returns to step 308. .. Upon receiving the advice screen information and the advice voice, the terminal 20 displays the advice screen (details will be described later) shown in FIG. 21 on the display unit 25 as an example, and reproduces the advice voice. In response to this, the builder whose advice screen is displayed on the terminal 20 tries to practice the advice displayed on the advice screen. As described above, the information indicated by the advice is information indicating the know-how for improving the work efficiency obtained when a skilled builder carries out the corresponding construction. Therefore, by practicing the advice displayed on the advice screen, the effect of improving the work efficiency for the corresponding construction process can be expected.

On the other hand, in step 336, the presentation unit 11G determines whether or not all the construction work other than the "inspection table confirmation" step at the corresponding site has been completed, and if a negative determination is made, the process returns to step 308, while returning to step 308. When the determination is affirmative, the process proceeds to step 338.

In step 338, the presentation unit 11G uses the inspection result information stored in the storage unit 13 in the above process to show an inspection table screen in a predetermined format including all inspection results. Create screen information. Then, in the next step 340, the presentation unit 11G transmits the created inspection table screen information to the terminal 20 of the builder who carries out the "inspection table confirmation" process in the corresponding construction via the communication I / F unit 18. The transmission is performed, and then the process proceeds to step 342. Upon receiving the inspection table screen information, the terminal 20 displays the inspection table screen (not shown) on the display unit 25. Then, the contractor whose inspection table screen is displayed on the terminal 20 confirms the inspection results of each process displayed on the inspection table screen, and then provides construction support for the inspection result confirmation information indicating that the confirmation has been performed. It is transmitted to the device 10.

Therefore, in step 342, the reception unit 11H waits until the inspection result confirmation information is received, and in the next step 344, the reception unit 11H stores (registers) the corresponding inspection result information in the inspection result database 33G. After that, the construction support process is completed.

Next, with reference to FIG. 15, the operation of the terminal 20 when executing the navigation process will be described. In addition, here, the operation of the terminal 20 possessed by the builder who carries out the process of "inspection table confirmation" will be described.

In step 400 of FIG. 15, the control unit 21A controls the display unit 25 so as to display a predetermined initial screen, and in the next step 402, the control unit 21A is instructed to execute the navigation service. stand by. FIG. 16 shows an initial screen according to the present embodiment. As shown in FIG. 16, in the initial screen according to the present embodiment, a selection area 25A for selecting a language to be applied on the navigation screen is provided, and a navigation service start designated when instructing execution of the navigation service is started. Button 25B is displayed. When the initial screen shown in FIG. 16 is displayed, the builder specifies the button on which the language name to be applied is displayed on the navigation screen, and then specifies the navigation service start button 25B. When the navigation service start button 25B is specified, step 402 becomes an affirmative determination and the process proceeds to step 404.

In step 404, the control unit 21A sends the above-mentioned navigation request information to the construction support device 10 via the wireless communication unit 27 together with the site information indicating the construction site, its own installer ID, and the language information indicating the language to be used. Send. As described above, when the construction support device 10 receives the navigation request information, it transmits the navigation screen information indicating the navigation screen to the terminal 20.

Therefore, in the next step 406, the control unit 21A waits until the navigation screen information is received, and in the next step 408, the control unit 21A uses the received navigation screen information to display the first page of the navigation screen. The display unit 25 is controlled so as to start the display from.

With the above control, the navigation screens shown in FIGS. 17 to 20 are sequentially displayed on the display unit 25 of the terminal 20 as described above. The navigation screen 25C shown in FIG. 17 is an example of a navigation screen relating to the measurement of "the bottom surface of the foundation to the inner surface under the frame", which is a part of the process of "window measurement" in the process of "confirmation of fit". Further, the navigation screen 25D shown in FIG. 18 is an input area for inputting measurement results in the process displayed on the navigation screen 25C shown in FIG. 17 (the step of measuring "the bottom surface of the foundation to the inner surface below the frame"). This is an example of a navigation screen provided with 25E. The builder who has referred to these navigation screens performs measurement according to the display contents of the referred navigation screen, and inputs the measurement result to the input area 25E.

Further, the navigation screen 25F shown in FIG. 19 is an example of a navigation screen displayed when starting the process of installing the “bathtub”. As described above, in the present embodiment, the construction support device provides individual process end information indicating that the immediately preceding process has been completed when the designated input for specifying the execution start of the next process is received on the navigation screen. It is transmitted to 10. Therefore, on the navigation screen 25F shown in FIG. 19, the bathtub construction start button 25G specified when starting the bathtub construction is displayed, and the installer presses the bathtub construction start button 25G when starting the bathtub construction. specify.

Further, the navigation screen 25H shown in FIG. 20 is an example of the navigation screen displayed in the process of “inspecting the waterproof pan joint”. In the navigation screen 25H shown in FIG. 20, a photographed image obtained by actually photographing a part similar to the part to be inspected is displayed as a model photograph. Further, on the navigation screen 25H, a captured image area 25I on which the captured image taken by the camera 28 of the terminal 20 is displayed, and a shooting button 25J designated when performing shooting are displayed. Therefore, the installer sets the magnification of the terminal 20 and positions the terminal 20 so that the composition of the photographed image displayed in the photographed image area 25I substantially matches the composition of the model photograph, and then the photograph button 25J. To specify. By this operation, it is possible to take an inspection image on the construction object extremely accurately. The navigation screen for inputting the inspection result is not limited to the one for inputting the photographed image shown in FIG. 20 as an example, and although not shown, information indicating whether or not the inspection result is acceptable is displayed. Needless to say, there is also a navigation screen for input.

Each image on the navigation screen shown in FIGS. 17 to 20 is based on the "explanatory image" in the navigation information. Further, the text information on the navigation screens shown in FIGS. 17 to 20 is based on the "explanatory text" in the navigation information.

In the next step 410, whether or not the control unit 21A has input the measurement result, the inspection result, or the designated input for designating the start of execution of the next process to the displayed navigation screen. Is determined, and if a negative determination is made, the process proceeds to step 412.

As described above, in the construction support process according to the present embodiment, when the reference time elapses for the process being carried out, it is considered that the work efficiency in the process is below a predetermined level, and the advice screen information. And each information of the advice voice is transmitted from the construction support device 10.

Therefore, in step 412, the control unit 21A determines whether or not the advice screen information has been received from the construction support device 10, and returns to step 410 if a negative determination is made, while a step if an affirmative determination is made. Move to 414.

In step 414, the control unit 21A controls the display unit 25 so as to display the advice screen indicated by the received advice screen information, and sets the speaker 41 so as to emit the voice by the advice voice received together with the advice screen information. Control and then return to step 410. FIG. 21 shows an example of the advice screen 25K according to the present embodiment.
